European DS games on cartridge should work fine on any DSi LL. The only region specific concerns you might have is the online content it can access.
yes yes you can
No, dsi games work in a 3ds, wont appear 3d though, but the dsi does not have the ability to play 3ds games.
There is no "DSi lite" console but if you mean the DSi XL, it is fully compatible with DSi games(although you'll have to buy them twice if you want a copy on a DSi and a DSi XL)
The DSi does not have a Gameboy advance slot so you cannot play Gameboy advance Pokemon games. All other Pokemon games that can be played on the regular DS or DS lite can be played on the DSi. There are no Pokemon games that utilize the DSi's camera function as of yet.
The DSi XL is not region locked, it will play games from any region. The exception is for games marked as 'DSi-enhanced' such as Pokemon Conquest. These work in a regular DS or 3DS, but not a DSi from the wrong region.
yes :)
The only games you can play are games made for the Nintendo DS. All other games are not able to be played on the DSi.
yes it can
The DSi doesn't have a gameboy slot, so GB, GBC or GBA games can't be played on it at all.
Yes, you can use ds games on the dsi. My friend's sister got one for her birthday and she said you can use them in the dsi. But the Dsi's do not fit in a Ds case.
could u tell me if uk games will play in usa dsi thankyou
DS games can be played on the 3DS but 3DS games can't be played on the DS.
